Nicholas Carr on how the internet is damaging our brains

US technology writer Nicholas Carr is worried about what the internet is doing to our brains.

“The seductions of technology are hard to resist,” Carr says in his new Book ‘The Shallows’, which has sold an estimated 50 000 hardback copies in the United States alone.

But he thinks it’s time to start trying.

In a speech at last week’s Seoul Digital Forum, Carr restated his concerns that the web is affecting the way people think and feel — and even changing the physical make-up of their brains.

Every new technology in history — like the map and the clock — has changed the way people think, but Carr sees special dangers in the internet.

He got his first PC back in the 1980s and was an avid net user until “a few years ago, I noticed some disturbing changes in the way my mind worked. I was losing the ability to concentrate.”

While the Internet has enormous benefits in delivering incredible amounts of information at incredible speed, it’s also a distracting and interruption-rich environment.

Carr said it encourages quick shifts in focus, discourages sustained attention and the ability to think deeply and creatively about one topic.

Popularity-driven search engines, in one of the ironies of an information-rich internet, worsen the problem by leading everyone to the same sources, he said.

Social networks, while pleasurable and fun, increase distractedness by bombarding users with brief bits of information.

“We take in so much information so quickly that we are in a constant state of cognitive overload,” Carr argued.

“Multitasking erodes cognitive control. We lose our ability to say that this is important, this is unimportant. All we want is new information.”

In contrast, when readers open a printed book, “there’s nothing else going on except words on a page, no distractions. It helps train us to be deep thinkers.”

Carr, 52, said he’s not optimistic society will switch off en masse but it’s important to look clearly at what it might be losing.

And he doesn’t feel quite so lonely now that some other authors and TV programme-makers have tackled the same subject. “There are signs, still sporadic and small, that people are beginning to question the effects of technology.”

Since the book came out, he said, he had heard from several companies struggling with otherwise intelligent employees who were unable to focus and concentrate on problem-solving.

Carr admitted he himself has not had great success in limiting the time he spends online. But the biggest change he made as a writer and researcher was to use the web only to track down source material.

“Then I’d make an effort to actually read those things in print. I did find that made a big difference in my ability to be attentive and a thorough reader and hopefully a deeper thinker.”

But Carr said it was not just a matter of individual choice. If friends, colleagues and employers were constantly on line, “then you feel in many ways compelled to do so even if you don’t want to, because you don’t want to damage your career or your social life”.

The author said he had no simple formula for change. But companies could “start sending a signal thats it’s OK to be disconnected sometimes, it’s OK if you don’t respond to every email within 45 seconds or whatever”.

Employers, governments and schools could also start rewarding and encouraging people to switch off.
